The study's lead author, Alexandra Brodsky, argues"stealthing" is a form of sexual assault.

In the study, one of the victims Brodsky interviews called the act "rape-adjacent."

Another victim described it as a "blatant violation of what we'd agreed to."

Brodsky also notes the troubling trend of men encouraging others to "stealth" their partners in online forums, because they think it's a man's right to "spread one's seed."

In the report, Brodsky notes that since existing laws in the U.S. don't necessarily cover "stealthing" as a form of sexual assault, a new statute should address it.

"One of my goals with the article, and in proposing a new statute, is to provide a vocabulary and create ways for people to talk about what is a really common experience that just is too often dismissed as just 'bad sex' instead of 'violence'," Brodsky told the Huffington Post.

While the law may be behind in the U.S., in January, a man in Switzerland was convicted of rape after removing a condom during sex without his partner's knowledge.

The court argued the woman would have refused to have sex if she knew the condom was removed.
